Q1: Dab tsi yog Q235B Welded yeeb nkab?
A1: Q235B Welded yeeb nkab yog hom carbon steel yeeb nkab ua los ntawm q235b steel, uas yog ib qho cov hlau uas muaj cov hlau. Nws yog tsim los ntawm dov thiab vuam hlau coils lossis cov phaj. Cov khoom siv no tau siv dav siv hauv kev tsim kho, tshuab, thiab kev txua dav dav vim nws lub zog zoo thiab lub zog zoo thiab Weldability. Tus "Q" sawv ntsug rau kev paib muaj zog tsawg kawg yog los lub zog muaj zog ntawm 235 MPa, thiab "B" yog hais txog qib zoo. Nws muaj qhov nruab nrab lub zog thiab tuaj yeem tiv taus ntau yam txheej txheem fabrication. Piv rau cov kav dej seamless, cov kav dej welded muaj nqi ntau dua rau cov ntawv thov tsis muaj zog.
Q2: Cov khoom siv tshuaj muaj pes tsawg leeg ntawm Q235b Steel?
A2: Cov khoom siv tseem ceeb ntawm Q235b Steel muaj xws li carbon (c), silicon (si), manganese (mnc), phosphorus (p), thiab leej faj (s). Cov ntsiab lus carbon feem ntau yog feem ntau hauv qab 0.20%, ua kom pom zoo weldability thiab muaj meej. Silicon thiab manganese txhim kho lub zog thiab hardness, thaum phosphorus thiab leej faj yog tswj hwm ua impurities. Cov ntsiab lus siab tshaj plaws yog 0.045%, thiab leej faj yog txwv rau 0.045% kom tiv thaiv brittleness. Cov nyiaj me me ntawm lwm cov ntsiab me me kuj tseem nyob, tab sis lawv tsis hloov cov khoom siv cov khoom ntiag tug.
Q3: Cov khoom siv neeg kho tshuab ntawm Q235B Welded yeeb nkab?
A3: Q235B Welded yeeb nkab muaj tsawg kawg vim muaj lub zog ntawm 235 MPa thiab lub tensile lub zog xws li ntawm 375 txog 500 MPA. Nws elongation thaum so yog li 26%, qhia tau qhov ua kom zoo. Cov khoom pov thawj pom kev nyuaj thiab cuam tshuam tsis kam, ua rau nws haum rau cov ntawv thov kev tsim qauv. Nws tuaj yeem ua kom txias thiab welded yam tsis muaj lub zog tsis zoo. Txawm li cas los xij, nws txoj kev nruj me me txo qis qis heev kub, txwv nws siv hauv ib puag ncig cryogenic.
Q4: Yuav ua li cas Q235B Welded yeeb nkab tsim?
A4: Q235B Welded yeeb nkab yog tsim los ntawm high-zaus induction induction induction (HFIW) lossis submerged arc vuam (pom). Cov txheej txheem cuam tshuam nrog uncoiling steel strips, tsim lawv mus rau hauv ib lub cylindrical puab, thiab vuam cov npoo. Tom qab vuam, cov yeeb nkab undergoes sizing, ncaj, thiab txiav mus rau qhov uas yuav tsum tau ua. Tsis yog-kev sim ua phem (ndt) zoo li ultrasonic lossis xoo hluav taws xob tshuaj xyuas kom Weld ncaj ncees. Cov kev kho saum npoo xws li Galvanizing lossis xim yuav siv rau corrosion tsis kam.
Q5: Cov kev siv ntawm Q235B welded yeeb nkab?
A5: Q235B Welded yeeb nkab yog dav siv nyob rau hauv kev tsim kho rau scaffolding rau scaffolding, cov qauv coj ua, thiab fencing. Nws tseem ua haujlwm hauv kev tsim khoom machinery tsim, dej thiab roj thauj khoom, thiab cov khoom siv hauv kev ua liaj ua teb. Vim nws cov khoom muaj nqis thiab muaj txiaj ntsig zoo, nws yog qhov kev xaiv nrov rau cov raj luv-rau-nruab nrab. Ib qho ntxiv, nws ua haujlwm ua cov khoom siv rau cov rooj tog, chaw tsheb, thiab lub hom phiaj dav dav.
